A CoII-based metal–organic framework based on [Co6(μ3-OH)4] units exhibiting selective sorption of C2H2 over CO2 and CH4†
Abstract
By virtue of unique planar [Co6(μ3-OH)4] cluster units, a new microporous isonicotinate-based framework with high thermal and framework stabilities was achieved. The guest-free framework demonstrates high capacity and selectivity for C2H2 relative to CO2 and CH4 at room temperature, which was further understood by GCMC simulation.
